3.CHECK HARNESS AND CONNECTOR (POWER BACK DOOR SENSOR ASSEMBLY - POWER BACK DOOR UNIT ASSEMBLY [POWER BACK DOOR ECU] AND BODY GROUND)

  1. for LH:

    1. Disconnect the S24 power back door sensor assembly LH connector.

    2. Disconnect the L52 power back door unit assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      S24-1 (OSL) - L52-15 (OSL)
      		Always
      		Below 1 Ω
      S24-2 (OSLE) - L52-14 (OSE)
      		Always
      		Below 1 Ω
      S24-1 (OSL) - Body ground
      		Always
      		10 kΩ or higher
      S24-2 (OSLE) - Body ground
      		Always
      		10 kΩ or higher

  1. for RH:

    1. Disconnect the S23 power back door sensor assembly RH connector.

    2. Disconnect the L52 power back door unit assembly connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      S23-1 (OSR) - L52-13 (OSR)
      		Always
      		Below 1 Ω
      S23-2 (OSRE) - L52-14 (OSE)
      		Always
      		Below 1 Ω
      S23-1 (OSR) - Body ground
      		Always
      		10 kΩ or higher
      S23-2 (OSRE) - Body ground
      		Always
      		10 kΩ or higher
